What applying on Ashby looks like

Ashby-hosted postings sit at jobs.ashbyhq.com/<company> or embedded on the company site. The form asks for a resume, contact details, and custom questions, and Ashby will attempt to parse the resume to prefill fields. No account is required to apply. Some employers turn on LinkedIn or Google-based autofill for the contact fields. Ashby does not give applicants a persistent login or dashboard by default, so tracking a submitted application means watching your email for replies rather than checking a status page. Multi-step forms (a screening question set before the main form) are more common on Ashby than on Greenhouse or Lever.

Jobless extension autofill: yes
